Choose the correct option. On an average, a content developer can develop 6 questions in an hour. Resource manager wants to complete the project of 2400 questions in 20 hours. How many developers should he take in his team?

(a) 30
(b) 20
(c) 40
(d) 10
Correct option: (b) 20
Given,
1 person – 1 hour – 6 questions
x persons – 20 hours – 2400 questions
Thus, x = (2400/6) × (1/20)
x = 400/20
x = 20
Therefore, 20 developers should be taken for the team.
